How biodegradable plastic bags don’t live up to their name

The average person uses a typical plastic bag for as short a time as 12 minutes before throwing it away, never thinking of where it may end up. biodegradable plastic bags

Yet once consigned to a landfill, that standard grocery store tote takes hundreds or thousands of years to break down — much more than a human lifetime. Bags make up an alarming amount of the plastic found in whale stomachs or bird nests. And it’s no wonder — globally, we use between 1 and 5 trillion plastic bags each year.

Biodegradable plastic bags are marketed as more eco-friendly solutions. Able to break down into harmless material more quickly than traditional plastics. One company claims their shopping bag “will degrade and biodegrade in a continuous. Irreversible and unstoppable process” if it ends up as litter in the environment.

Biodegradable bags that had been left underwater in a marina could still hold a full load of groceries.

In a study published this week in Environmental Science and Technology, researchers put supposedly eco-friendly bags made from various organic and plastic materials and sourced from U.K. stores to the test. After three years buried in garden soil, submerged in ocean water, exposed to open light and air or stashed in a laboratory, none of the bags broke down completely in all the environments.

In fact, the biodegradable bags that had been left underwater in a marina could still hold a full load of groceries.

A polymer is a repeating chain of chemicals that makes up a plastic’s structure. Whether biodegradable or synthetic.“What is the role of some of these really innovative and novel polymers?” asked Richard Thompson, a marine biologist from the University of Plymouth and the study’s senior author.

“They’re challenging to recycle and are very slow to degrade if they become litter in the environment,” Thompson said. suggesting these biodegradable plastics may be causing more problems than they solve.

What the researchers did

The researchers collected samples of five types of plastic bags.

The first type was made of high-density polyethylene — the standard plastic found in grocery store bags. It was used as a comparison for four other bags labeled as eco-friendly:

A compostable bag made from plant products

A biodegradable plastic bag made in part from oyster shells

Two kinds of bags made from oxo-biodegradable plastic, which contain additives that companies say helps plastic break down faster

Each bag type was placed in four environments. Whole bags and bags cut into strips were buried in garden soil outdoors, submerged in salt water in a marina, left exposed to daylight and open air, or sealed in a dark container in a temperature-controlled lab.

What the scientists found

Even in a tough marine environment, where algae and animals quickly covered the plastic. Three years wasn’t long enough to break down any of the plastics except for the plant-based compostable option. Which did disappear underwater within three months. The plant-derived bags, however, remained intact but weakened when buried under garden soil for 27 months.

The only treatment that consistently broke down all of the bags was exposure to open air for more than nine months. And in that case even the standard, traditional polyethylene bag disintegrated into pieces before 18 months had passed.

“I would take that timescale to be too long for these products to be regarded as providing an environmental advantage,” Thompson said.

Even if these bags take less time to break down than traditional plastic bags. As litter they would still have enough time to become potentially deadly food for ocean animals like seabirds, whales, turtles or fish. Moreover, they would still be an eyesore and take up space at waste facilities for months or years.

And when some of the plastic bags did seem to break down. Such as the bags left to the open air, it was unclear if the disintegration was complete.

“Did the plastic that was lost just become smaller pieces of plastic?” Kalow asked, “Or did it become molecules that could dissolve in water and be consumed?”

Future studies, she said, should dig into the fate of those disintegrated plastic particles. To ascertain whether they truly break down and disappear — or become microplastics and harmful chemicals.

Why it matters about biodegradable plastic bags

Even standard plastic bags can’t be recycled from your home recycling bin. So most end up in landfill or are swept away by water or wind, becoming litter.

Labels like “biodegradable,” “compostable” or even “recyclable” are theoretical — they don’t reflect the reality of what happens to the materials.

Biodegradable and compostable bags are meant to solve these problems, but the study indicates that’s not the case so far.

These alternative bags aren’t meant to end up as litter in the street or in the natural environment — ideally. They’d all be treated just as manufacturers expect. Biodegradable bags would be landfilled or, in some cases, recycled into new plastics — at least in theory.

But “even if we can make something that’s recyclable.

That doesn’t mean any commercial recycling plant would be interested in dealing with it,” Kalow said. Biodegradable plastics can’t generally be recycled with other plastics — in fact, they can ruin other batches of recyclable plastic, degrading the product until it becomes unusable.

Meanwhile, the eco-conscious should hope their compostable bags end up in industrial composting facilities where high temperatures and favorable conditions for bacteria and other living things would break them down. (Compostable bags in chilly, oxygen-starved landfills can actually be preserved rather than destroyed.

These are the real problems, Thompson said. Labels like “biodegradable,” “compostable” or even “recyclable” are theoretical — they don’t reflect the reality of what happens to the materials we throw away or litter into the oceans, and they don’t help people accurately understand how to get rid of them.

Three years after the researchers’ plastic bags were buried or submerged, they were nearly as useful — and as harmful — as the day they were made.biodegradable plastic bags

Some simple solutions might help. Thompson suggested that standardized products, made of the same sets of materials, could streamline our waste management systems and allow much more of our waste to be profitably recycled. Kalow, the polymer chemist, said there may yet be hope for new, improved biodegradable plastics if only we could discover that technology.

In the meantime, it doesn’t hurt to remember your reusable bag on your way to the store.

Are bioplastics and biodegradable plastics really better?

While public pressure has made companies appear to be more environmentally friendly. Most haven’t cleaned up their act. They’ve only created more confusing terms, greenwashing their products to make us feel like we’re acting responsibly. Plastic is made of artificially created chemicals “that don’t belong in our world and don’t mix well with nature.” After we use plastic–sometimes only for a few seconds–we throw it away. These plastics are a big source of pollution, getting into our food and water. It’s creating toxic health hazards for neighboring communities as part of their production, and disposal and killing marine wildlife.biodegradable plastics

The bottom line: the best solution is to avoid single-use plastics. No matter what material they are made from. It’s the only real way to prevent pollution and waste. When plastic is unavoidable. It’s vital to understand what the labeling actually means. Biodegradable plastics are very rarely recyclable, and biodegradable does not mean compostable. So they often up in the landfill. Compostable and bioplastic goods can be a better choice than biodegradable ones. But often still end up in landfills unless you can compost appropriately.

Why? There’s an important difference between what makes conventional plastics, biodegradable plastics, and bioplastic. And what happens when we’re done using them.

Conventional plastics are made from products derived from petroleum. The US Department of Energy reports that plastics are mostly produced from from natural gas processing. And feedstocks derived from refining crude oil, these are the ingredients that last forever in our environment. They take hundreds of years to break down and never completely decompose. They just become smaller and smaller pieces that are impossible to remove from the environment. Some plastics are known to be toxic, and as they break down. Plastic bits become food for organisms up and down the food chain.

Biodegradable plastics are made from the same materials as conventional petroleum based plastics. But with even more chemicals. These extra chemicals cause the plastic to break down more rapidly when exposed to air and light. Some biodegradable plastics fragment rather than biodegrade, due to the addition of oxidizing agents (found in “oxo-degradable plastics”). By fragmenting, rather than degrading, they break into small pieces which can pollute soils.

Increase risk of ingestion for animals and end up in our oceans and waterways. These kind of plastics are impossible to recover for recycling and aren’t suitable for composting. The prefix “bio” can be very misleading: plastics do degrade, but not into something biological. It breaks into smaller and smaller pieces of plastic.

Unfortunately, recycling your ‘biodegradable’ plastics isn’t a great answer to this issue.

Most biodegradable plastics have a #7 recycling code on them. Which places them in the ‘Other’ category of plastics. #7 plastics are generally not accepted for recycling by local municipal recyclers. Due to the addition of chemical additives.

Bioplastics and ‘compostable’ plastics tend to be made from plant biomass. Such as corn starch, sugar cane or wheat, and should either completely and rapidly break down biologically. Or be compostable. This means they are supposed to break down into biological elements, unlike conventional plastics. However, while some bioplastics can be composted and do not harm the quality of compost. Others leave toxic residues or plastic fragments behind, making them unsuitable if your compost is being used to grow food.

Additionally, the use of plant material for bioplastics causes concern including the use of genetically modified crops. And the use of farmland that could be used to grow valuable food crops, deforestation. Use of fresh water supplies, soil erosion, fertilizer use (which comes from petrochemical sources), food security and more.

Bioplastics cannot be recycled with standard plastics as the additives in bioplastics can make the recycled product less durable.

Composting bioplastics is also complicated. Most bioplastics will only compost in commercial (municipal) composters. Commercial composters reach temperatures and humidity levels you would be unable to achieve in a standard garden composter. So your bioplastics may never break down at home. Some commercial composters, like those in Northern California. Have to remove bioplastics like compostable utensils because even their temperatures and humidity levels will not break down these products.

So, is sending these items to landfill the best way to dispose of them? In a landfill, they won’t contaminate recycling or compost streams. But for biodegradation to occur, three basic resources are required – heat, light and oxygen. In a landfill site, waste is entombed, creating a complete absence of light and oxygen. If a biodegradable plastic or bioplastic ends up in a landfill site it may never decompose.

It’s clear: we can’t recycle or compost our way out of the plastics issue – and that holds true for new biodegradable plastics and bioplastics.

Polyglycolic Acid

China’s plastic-polylactic acid ban

Degradable plastics can replace traditional petrochemical plastics in plastic bags, disposable tableware, mulch and other fields.

with a market potential of tens of billions. regions with conditions are encouraged to explore “plastic- polylactic acid (PLA) bans.”

Since 2014, Jilin Province, Nanle County, Henan, and Hainan Province have successively introduced ” The “ban on plastic- polylactic acid (PLA) ”

prohibits the production, sale, and use of non-degradable disposable products, which has promoted the development of the local degradable plastic industry cluster.

Based on its national bio-based material industrial base, Nanle County has the conditions to promote degradable plastics.

In March 2018, it issued the “Implementation Opinions on the Control of White Pollution and Promotion of the Use of Disposable Degradable Plastic Products (Trial)”.

Gradually implement the “ban on plastics”.

At present, more than ten projects have been completed in the Nanle Bio-based Materials Industry Base, the industrial chain is basically closed, and the end products are abundant.

We have reached cooperation with a number of downstream application companies to meet local consumption and radiate outwards. The products are sold throughout the country. And foreign markets such as Europe and the United States.

In February 2019, Sale and Use of Disposable Non-degradable Plastic, which clarified the “plastic ban” advancement schedule.

2025 Before the end of the year, the entire province has banned the production,

And use of plastic products listed in the “Hainan Province Prohibition of Production and Sale of Disposable Non-degradable Plastic Products List “.

At present, Hainan Province is in the process of attracting investment for all biodegradable enterprises. Hainan Province uses about 110,000 to 120,000 tons of disposable non-degradable plastic bags and products each year.

The Hainan “plastic ban” will definitely drive the formation of a new degradable plastic industry cluster.

The 2019 Degradable Plastics Technology and Market Forum will be held in Kunming, Yunnan from April 24-25. A special discussion session will be set up to discuss the development opportunities of degradable plastics in Yunnan.

biodegradable plastics

Do we need biodegradable plastics?

In Frank Capra’s classic movie “It’s A Wonderful Life,” Sam Wainwright encourages George Bailey to invest in the exciting world of plastics. “It’s the biggest thing since radio,” Sam tells George, “and I’m lettin’ you in on the ground floor.”

We can only imagine what Sam would have thought about biodegradable plastics. And how he would have pitched it to his old friend. When scientists discovered they could make polyesters out of plants in the late 1980s. He might have said something like, “It’s the biggest thing since the PC.” And it was, in concept, but as is often the case with “miracle” solutions, the reality rarely lives up to the hype.

As it turns out, producing PLA, as opposed to traditional plastic, has been better from a fossil-fuel perspective.

Because it’s a bio-based polymer, it doesn’t require any oil as a raw material. Compare that to conventional plastic packaging, which uses 200,000 barrels of oil a day in the United States [source: Royte]. Nor does it demand as much energy — energy that comes from coal-burning power plants — to produce. According to some estimates, making PLA uses 65 percent less energy than producing conventional plastics [source: Royte]. That also means fewer greenhouse gases and less of a contribution to global warming.

First, let’s recap the promise of plastic made from polylactic acid (PLA), a polymer derived from plant sugars. When agricultural giant Cargill developed PLA, it touted two clear benefits. First, Cargill argued, the starting material for the polymer is corn, a crop produced by the billions of bushels every year. In other words, PLA comes from a renewable resource, unlike traditional plastic, which begins its life as oil made from fossil fuels during the refinery process. Second, PLA breaks down into water and carbon dioxide when exposed to bacteria. That makes corn-based plastic biodegradable, which makes it much more environmentally friendly.

Oxo-degradable plastic

It was another type of biodegradable plastic, isn’t much better. Although it can be recycled as part of a normal plastic waste stream, it’s made from a byproduct of oil or natural gas, so it still relies on a nonrenewable resource. And, as its name suggests, it decomposes best in the oxygen-rich environments provided by large industrial composting tanks, equipment not found in typical landfills or backyards.

But PLA-based packaging does require a controlled environment in order to break down. The bacteria that decompose the plastic can’t do their work. Unless all oxygen is removed and temperatures reach at least 140 degrees Fahrenheit (60 degrees Celsius) for 10 consecutive days. In such conditions, the plastic will biodegrade in fewer than 90 days. A landfill, however, can’t deliver these conditions. Neither can a typical home-composting operation. In either setting, PLA hangs around just as long as petroleum-based plastic — 500 years or more. And PLA that makes it to recycling centers causes other problems. Recyclers can’t bundle PLA with traditional plastic, so they consider it a contaminant.

So, given the reality of different biodegradable plastics, do we really need them?

In their current forms, perhaps we don’t. But that state of affairs doesn’t necessarily indicate the shape of biodegradable plastic to come. In the meantime, recycling programs could be tweaked to accommodate corn-based biodegradable plastic, perhaps expanding to a three-bin recycling collection system: one for traditional plastics, one for biodegradable plastics. Which would be delivered to a commercial composting facility, and one for whatever is left.

That may not seem very exciting to get-rich-quick entrepreneurs like Sam Wainwright, but it’s a step in the right direction.

100% Biodegradable

Are Plastics Biodegradable?

Some things biodegrade faster than others – many vegetables can biodegrade in a month or so while leather shoes can take many decades. Other than the material itself, the key to biodegradability is the environmental conditions surrounding the material.plastics

Why? (OK, a little more science …)

To biodegrade, organic materials require air, water, light or a combination of these elements. So microorganisms can do their job. Remove any or all of these elements, and biodegradation can be slowed dramatically. That’s why our Declaration of Independence in the National Archives. It made from parchment (thin animal skin), is displayed in a carefully controlled atmosphere. Air, water and light would cause it to biodegrade.

Another example … remember the Dead Sea Scrolls? Made from parchment and papyrus, both materials that can biodegrade, the scrolls survived two millennia in caves. Once removed from the caves, they began to biodegrade quickly.

What’s this have to do with plastics?

Can air, water and light cause plastics to biodegrade? In other words, are plastics biodegradable?

While some do so very slowly if exposed to air, water and light – both types are best recycled or used for their stored energy.Many plastics do not biodegrade to any significant degree, regardless of environmental conditions.

Some plastics have been engineered to biodegrade reasonably quickly – and here’s the important part – in a large composting facility. That intentionally accelerates biodegradation in a highly controlled environment using copious air, water and light.

These plastics also will break down eventually if left alone in the environment. But much more slowly since the environment does not “intentionally accelerate” biodegradation. However, similar to other biodegradable materials, they likely will not break down in modern landfills that basically store waste, and are designed to retard biodegradation.

Some materials such as glass, aluminum and many plastics do not “bio” degrade. Although they will “degrade” physically over a very long time (I also will tackle this topic in the future).

So … biodegradability of plastics depends largely on the type of plastic and where it ends up.

When science meets the law, labeling consumer products as “biodegradable” gets a little tricky (the topic of a future lesson).

That’s the scientific explanation in a nutshell. A few caveats:

Today there are only a handful of large composting facilities in the U.S. that accept consumer products.

Biodegradable plastics must be separated from plastics that are being recycled (another future lesson topic).

The Myth of Biodegredation

Myth: Waste simply biodegrades in the landfill.
Biodegredation

biodegrades Reality: Nothing biodegrades in a landfill because nothing is supposed to.Biodegredation
Biodegradation 101

Organic matter “biodegrades” when it is broken down by other living organisms (such as enzymes and microbes) into its basic components, and in turn, these molecules are recycled by nature into the building blocks for new life.

This process can occur aerobically (with the aid of oxygen) or anaerobically (without oxygen). Substances break down much faster under aerobic conditions because oxygen helps break the molecules apart.


Landfills excavations have uncovered some startling facts:

Modern landfills are designed to entomb municipal garbage safely and securely. Most landfills are anaerobic, because they are compacted so tightly that air cannot get in. Because of this, any biodegradation that does take place does so very, very, very slowly. Trash entering landfills essentially retains its original weight, volume and form for the entire active life of the landfill.

Newspapers are still readable after almost 40 years; ten-year-old carrots are brown on the outside but bright orange on the inside; and 20-year-old steaks still have meat on the bones.

Why aren’t materials – even raw organic debris – rapidly biodegrading in landfills?


The answer is simple: Many people believe that landfills are just big, carefully controlled
compost piles. They are not!


Micro-organisms in a compost heap are aerobic
and they biodegrade organic matter quickly and
efficiently outside. In compost piles, the garbage is
chopped, kept moist, oxygenated, and stirred.

The anaerobic microorganisms in a landfill just don’t receive the proper balance of moisture, nutrients,
and temperature to biodegrade organic matter. No
one chops garbage in a landfill or stirs it, and no one
adds fluids or oxygen- it is stable.


The dry and oxygen-poor conditions found in modern landfills cause organic matter to mummify rather than decompose. The result is very little biodegradation in a landfill.


But what about methane from landfills?

Landfills are the third-largest source of human-related methane emissions in the United States, accounting for approximately 17% of these emissions in 2009. Methane is a potent greenhouse gas.

Uncontrolled biodegradation in a landfill can cause methane gas emissions, ground water pollution, and unstable sub-soil conditions. As a result, modern landfills are kept dry and air-tight to try to prevent biodegradation.

Really old organic materials in landfills are slowly releasing methane today as they anaerobically degrade, but since we have started managing landfills more responsibly, we are learning that the legacy of poorly managed landfills is not sustainable. Even more importantly, we can capture the methane emissions from landfills and use them as a
significant energy resource.

This is why we encourage everyone to divert as much organic waste from landfills today.

All the plastic that has ever been created is still around today. Biodegredation

Petroleum biodegrades easily and quickly in its original form of crude oil. But when petroleum is processed into plastic, it is no longer biodegradable, and will remain in the landfill indefinitely.

Most plastics are stable in the landfill. The industrial processing they went through prior to their useful days converted them into forms unrecognizable to many microbes and enzymes.

Bioplastics like PLA are also stable in the landfill, even though they are made from renewable resources like corn.

Once PLA has been created, it is strong and rigid – and is designed to break down aerobically in a compost pile. So PLA will remain stable in a landfill and as far as we know, it does not contribute to landfill methane. Biodegredation

Composting Biodegredation

Composting, on the other hand, is the process of controlled biodegradation outside a landfill in an aerobic, outdoor compost site.

Compost can be used in farming, landscaping, gardening and soil conservation and is one the simplest and most effective ways to return carbon and structure to soils.

By carefully controlling compost inputs such as organics materials, wood chips, yard waste, food scraps, foodservice items, etc., and controlling the moisture content and oxygen levels at the site, composters transform biogegradable materials into useful compost.

Today, despite national progress on yard waste composting, more than 60 million tons of biodegradable materials (food scraps, wet & soiled paper, leaves and grass) are still being sent to landfills where they will sit in an airless, dry environment to be mummified. Biodegredation

Biodegradable ≠ Compostable ≠ Recyclable

“Compostable” products are biodegradable, but with an added benefit: when they break down in a compost pile, they release valuable nutrients into the soil, aiding the growth of trees and plants. These products degrade within several months in an industrial composting facility and produce no toxic residues. Biodegredation

Reduce, Reuse, Recycle is Best Solution for Landfills

Getting people to sort their trash accordingly is the new challenge. Plastics need to stay out of the compost and organic matter (and recyclables) need to stay out of the landfills. With landfills around the world reaching capacity, it’s time to think about where things go when we throw them “away”. Biodegredation

Application analysis of PLA material in e-cigarettes

1, because of its good oil absorption, traditional cigarettes, heating without burning are used

Through the above content, we have a basic understanding of PLA materials.In fact, the heated non-burning cartridge, and filter of traditional cigarette are applied to PLA materials. PLA material in e-cigarettes

In heated non-combustion smoke shells, there are basically cooling sections made of PLA material by folding. Disassembly articles show that the IQOS smoke bomb structure, contains PLA smoke oil filter, as shown in the figure below. From left to right, the structures are filter cotton, PLA smoke oil filter, hollow filter and tobacco fillet.

In addition, in the selection of materials for traditional cigarette filters, cellulose acetate filaments are the most widely used materials, but their degradation rate is slow.

Therefore, in recent years, PLA filaments have been used in cigarette filters, which have certain advantages in degradation, hydrophobicity, bacteria-inhibition, cooling and cost.It is worth noting that PLA material has a very high resistance to essential oils, that is. It has a good oil absorption.

In addition to biodegradability and biocompatibility, good oil absorption must be one of the reasons. Why soyee lobular e-cigarettes use PLA filters, to prevent oil leakage and condensate.

2. Not all PLA materials can absorb oil well

However, it is not possible to absorb oil by using PLA material. First, it has to be PLA fiber. Which can be produced by solution spinning, melt spinning (the main method), electrostatic spinning and other processing methods.

At the same time, its oil-absorbing performance is related to the shape structure of PLA fiber, and the pore structure of fiber membrane.

Some studies have compared the oil absorption performance, of pure PLA, PVA/PLA porous core shell, and PLA hollow porous fiber membrane. PLA material in e-cigarettes

The results showed that the PLA fiber membrane had oil absorption, the PVA/PLA porous core shell structure and the PLA hollow porous fiber membrane had better oil absorption. And the PLA hollow porous fiber membrane had better oil absorption performance than the PLA porous core shell structure membrane.

V. other applications of PLA materials

Benefiting from its excellent properties of biodegradability, biocompatibility, gloss, transparency, handle, and heat resistance. PLA material is being widely used in various industries, including 3D printing, apparel, packaging, and medical care, in addition to the e-cigarette industry.

WHY USE BIODEGRADABLE frash BAGS?

Biodegradable frash bags

White pollution is on the increase as a problem that is seriously impacting the environment across the world. biodegradable frash bags

With an increased awareness to the environmental problems that plague the globe, many are taking steps to find solutions.

Same Results

If you are concerned about using biodegradable frash bags for performance reasons, then you should know that the work just as well as traditional polyethylene garbage bags.

No Chemicals

If you are worried about your health, there are no chemical components involved in the monufacturing of biodegradable frash bags. In addition, there are no products that are petroleum-based, as well.

Rapid Degradation

It are designed to decompose quickly. Some breakdown completely in as little as 12-24 months when placed in soil, thanks to the microorganisms in the soil.

Composting

Certain types of biodegradable bags, which use OXO-biodegradable plastics, can be composted. When this type of plastic is exposed to oxygen or microorganisms that emit oxygen, there is a reduction in the amount of time that it takes for the bag to break down.

Not Petroleum-based

The over reliance on fossil fuels is having a negative impact on the environment. However, biodegradable rubbish bags are helping with this problem because they are not made from materials that come from oil.

Compostable bags are made from a blend of PBAT, PLA and CORNSTARCH.  These ingredients together create a material with strength, shape and compostability.

With all their benefits, biodegradable plastic reduces the waste generated every day. And can easily be composted, this biodegradable plastic can be collected along with the yard waste or food scraps and sent to compost heaps.

The compost obtained from there could be used for agricultural purposes. This is will not just keep the environment clean, but also keep us healthy and reduce dependence on petroleum based products. In other words, biodegradable plastics offer a win-win solution to the problem of white pollution.
